you can use the processing tool 'geometry by expression' , starting from existing points on the line, the function is called project(point,distance,azimuth) you need to build your lines

select feature use name = yourname

Its even simpler in arcgis, you'll have to first type in the search box "create routes" where you can select the polyline layer and convert it to a route specifying its start and end and then type in the search box "locate features along route"

QGIS's own command "points along geometry' you mentioned is made for a single point. It doesn't work for multiple points and lines. This great for me. I was looking for a long time. Thanks again. Noel

@@ibrahimgedik495 if you know how to do a bit of script you can use the function line_interpolate_point(geometry,distance) to create points using the attribute value in a table, you also need 'geometry by expression' to make it a point layer

@@StefanoVerugi In the more recent versions of QGIS, there is function called 'Interpolate point on a line' that does the same thing. But these two gives you only one point a time. We cannot get all the points at a time. Runnning batch process is also not an option when we have many points

@@sharmand5905 yes, in fact I was suggesting to use either geometry generator in layer styling pane or a virtual layer + spatialite

Make sure that your are working in UTM or change your file's crs to UTM zones

Thank you for the comment. It most probably could be but I don't have much coding knowledge to do something like that

@@noelvictor9132 after a little search I figured we can use line_locate_point in field calculator, together with closest_point. the second function projects the point onto the line, the first determines the distance of the projected from line origin easier than it sounds (I don't know much of coding either)

@@StefanoVerugi woah I'll try this

I personally don't know how to do that but you can try plex earth. If ever I get to confirm it I'll let you know.

Hello sir, I tried dragging a kml but it didn't work, however, I found that we can add google maps labels from map source in terra incognita so its easier to spot our desired area.

Thank you for your feedback, I'll take care of that from now on. Have a great day!

Chainage field contains length data. This is "shape Length" in Arcmap. It should be double/float.

Thank you for your comment, glad I could help.
